Huanyang Inverter control

Hey everyone,
I am having trouble controlling the HY inverter I am not using the USB device that most people use because I had this one already.
Also I am using a RPI 4 to run Linuxcnc. I am not sure what I need to change in the custom HAL files to access the inverter please see my attached files my device is on Bus 2 ID 4 at the top of USB.txt file but I have no clue how to identify it in the dev_tty.txt or if I did what would I need to change from the examples on the internet where the are USB0?
Any help is appreciated.

Thanks, That is what I thought I had the USB to Ethernet which I assumed was and RS485 but looks like that is not what I need. I just ordered the device that everyone else is using. I will give that a try when I receive it.

I ordered the other ones with the screw terminals 2 for 6 $ so is they fail or don't work I will get one like yours it is a lot cleaner.

I received the USB to tty and now I can see it on ttyusb0 but I have something wrong in the hal file
If someone will let me know what is wrong I would appreciate it.

# Include your custom HAL commands here
# This file will not be overwritten when you run PNCconf again
loadusr hy_vfd -n vfd -d /dev/ttyusb0 -p none -r 19200


net spindle-cmd-rpm => spindle-vfd.speed-command
net spindle-cw motion.spindle-forward => vfd.spindle-forward
net spindle-ccw motion.spindle-reverse => vfd.spindle-reverse

net on motion.spindle-on => vfd.spindle.on
set vfd.enable 1

@andypugh I have corrected that and try all different commands but I cannon get it to work in LinuxCNC I can get it to work on a terminal 
I know it is probably something dumb but I cant figure it out.   


 

There are no errors only no rotation.  I checked the halshow meter and some of the signals are not updating.  I missed the memo on updating the HAL file to connect any of the xxx.0.xxx so that may be the issue.  Is there an example of how that is done?  is it => like the pins?
